HENRY P. MGBRIDE, OF CHICAGO', ILLINOIS.

INSULATINGr-JOINT.

Specification of Letters Patent.

Application filed October 20, 1913. Serial N0. 796,232.

To all 'whom 'it may concern Be it known that I, HENRY P. MoBRIDE, a citizen of the -United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Insulating- Joints, of which the following is a specification. f

My improvement relates to insulating joints for electric fixtures.

The object of this improvement is to provide an insulating` joint which incorporates a hickey with said joint and provides a means for easily connecting and disconnecting electric wires in the fixtures.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter de scribed and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which- Figure 1 is a vertical section of an insulating joint embodyingmy invention, and illustrates its method of installation, Fig. 2 is a section of the same taken on line 2 2 in Fig. 1, Fig. 8 is a plan View of an insulating joint used to connect combination electric and gas fixtures which embodies my invention, and Fig. 4 is a section of the same taken on line 4-4 in Fig. 3.

The preferred form of construction as illustrated in the drawing comprises an annular insulating block 5 having a fixture connector embedded in its central portion and electrical wire connectors embedded in said block. In an insulating joint adapted for connecting electric fixtures, I employ the form shown in Figs. 1 and 2 in which the fixture connector 6 is embedded in the insulating block 5. At the upper end of fixture connector 6 is a loop 7 which is provided with an insulating covering 8 around its upper portion. The insulating material 8 engages the hoop end 9 of a connector 10 which is screw threaded on a ceiling plate 11, the latter being secured to the ceiling by means of conventional screws 12. The insulating material 8 on loop 7 is provided to insulate the fixture support 6 from the sup-f porting hook 9.

Threaded in the fixture connector 6 is the upper end of an electric fixture 13 which is provided with conventional fixture wires 14 which lead upwardly and around the between.

ably embedded in the insulating block but may be secured in the block 5 in suitable openings in any approved manner.

In the periphery of the insulating block 5 are provided a plurality of' recesses 17 which have openings leading therefrom to the con-y nectors 15. Binding screws 18 are disposed 'in the openings in block 5 with their heads disposed in recesses 17 and their inner ends threaded in sockets 16 securely holding the fixture wires in said sockets. The connectors 15 are also provided with sockets 19 which are adapted to receive the line wires 20. The sockets 19 are provided with binding screws 18 fitted therein in the same manner as binding screws 18 are fitted in sockets 16. With this construction it will be seen that the line wires 2O may be easily connected and disconnected when so desired thus doing away with the ordinary method of soldering the line wires and fixture wires at the insulating joint.

.In the form shown in Figs. 3 and 4 the fixture wires are not led to the interior of the fixture connector. In this construction the insulating block 5 is provided with electrical wire connectors 15 and the latter are provided with sockets 16 and 19 for the reception of the line wires and fixture wires in the same manner as that shown in Figs. 1 and 2. In this form a pipe line connector 21 is embedded in the upper end of insulating block 5 and a fixture connector 22 embedded in the lower end of the insulating block 5. Both of the connectors 21 and 22 are secured in the insulating block 5 in a manner to provide fluid tight joints there- Connectors 21 and 22 are secured in insulating block `5 in the conventional manner. T he only new feature in this form is the provision of the wire connectors 15.

While I have illustrated and described the preferred forms of construction for carrying my invention into effect, these are capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

y prising an annular' insulating block having Having described my invention what I' claim as new and desire to secure by Letters Patent is:

l. A device of the kind described cornprising an insulating block having recesses y in its outer side and an opening leading inwardly from each recess a fixture connector embedded in said insulating block; a plun rality of electric wire connectors embedded ing from said peripheral recesses to said downwardly extending recesses; electric wire Aconnectors in said downwardly extending recesses; screws extending through said `openings'threaded in said connectors and having their'heads ldisposed `in said peripheral recesses; and a fixture connector lfitted in said block, substantially as described.

In testimony whereof I have signed my iiain'e'tothis specification in the presence of two subscribing witnesses.
